Thisinvention relates to new and useful improvementsvin' adius'tabledoor locksof `the type adapted to ybe positioned in the wood work of adoor or other structure. An object of myinvention is to provide a lookmechanism for doors which `may be conveniently locked from Vone side sothat entry can not be made through the opposite side of the door withoutunlockingthe mechanism.

'Another object of my invention is to provide a locking mechanism whichmay be conveniently adjusted to tit various size open ings in doors orotherv structures.

Another object of my invention is to provide an adjustablelock whichmayybe con` veniently applied to door-Stiles of different widths withoutvarying vthe openings therein or structure thereof. y

Another object of my invention is to provide a door lock mechanism whichmay be conveniently adapted to `fit within theordinary openings of doorstiles without 'altera- `tion thereof.

With these objects the invention consists inthe novelconstruction andcombination of parts herein more `fully described, claimed, andillustrated, in the ,accompanying, drawings, showing the preferredvformof my inventiornfin which:

Fig. 1 is a vertical sectional view cfa Vlock embodying my invention;` ni Fig. 2 is a horizontal sectional View of the same, showing themannerin which it is 35 applied to a door-stile; and l l y y F ig. 3 isa perspective view of the same.

Referring to the drawing, the numerall represents `a face plate having atubular member 2 suitably clamped thereto, in which is provided aplurality of `slots 3. Slidably located inside the tubular member `2 iscasing 4, divided longitudinally into two sections and havinarraised'projection thereon which is a 4apted to engage with one of theslots 3jso as to maintain the said casing in a.` fixed position `withrelationship to the tubular member 2. The two sections of the casing 4are held in place by the tubular member 2 and by the end cap 6 which issuitably attached over the ends of the said sections.A The casing 4 isprovided with two turned under parts 7 ywhich lproject through slots 8located in tube-9, the said tube `being `,adapted to be moved backwardand forward inside (the` casing 4. Suitably clampedri'gidly totheforward en'd of the tube 9 is ring 1Q which has thej endv thereof turnedinwardly at 1l.

Located inside tube 9 and adjacent the' turned under parts 7 andcontacting therewith is a circular washer 12, against Vwhich one end ofspiral wire spring l'bears, the other end of said spring bearing againstthe inwardly projecting part 11 oi' the `ring 10. The said spiral spring1S'serves to maintain the parts ofthe lock just described 'in theirproper positions.

Extending through .the face plate 1, and inside thetubular'member 2, thering 10, and the tube@ is a plunger Mwhich is threaded and provided insections. which may be broken'ofi'l to permit vits being used with ydififerent size door stiles, as will be `explained hereafter. Screwed ontheplunger 14 andv located insidethe yring' V10 is a 'nut 'l5 which bearsLagainst the inwardly projectingpart 11 ofthe said ring. i i, p

Located inside the spiral wire spring 13 with its ends bearing againstlthen-washer 12 and the nut 15, a spiralspring 16V which tends to force`the plunger lioutwardly.

Secured to and located inside tube 9'by a suitable pin 17 isa lockingmember 18'which is provided withan `L-shaped slot 19 therethrough and asemicircular indentation in which a cam 2() fits.

The cam 20 is Uprwicled with a `square y shaped opening21 therethrough,in vwhich is inserted a spindlew22 having handles 23 at-` tachedthereon.The tube 9 is providedwith slots 24: which fare` located adjacent thecam 2() so that the saidA cam may turn for the p required distance. Thusby turning the handies 23'so that the spindle 22 turns, the cam 2O ismade to move the locking member 18 backwardly, and to compress spiral.spring 13, which upon the release of the handles brings the normalpositions. v

Movably extendingthrougha side plate 25 is a handle 26 which is` securedto a lever 27, having a pin .28 thereon which extends parts of the lockback to their through `a slot 29 located in plate 30, the` 1* latterhaving a pivotal motion. Y

Secured to the, plate '30 and extending through the L-shaped slot :19is` a cylinder 31 inside of which is located afrod 32, one end of whichrodis secured to aj lever bar 33. Secured to the bar 33 is a lslottedrod 34:, which extends loosely through a handle piece 35 lfastened tothe spindle v22. `Thus aby turning thel handle 26; the. rod V32`is ti t)moved upwardly inside the upwardly projecting part of the L-shaped slot19 thereby preventing the locking member 18 from be ing moved baekwardlywhich causes the mechanism to become locked.

Located inside one ot the handles Q3 adjacent the slotted rod 31 is alock cylinder 3G through which a, key may be inserted to turn the saidslotted rod in order that the rod 32 may be dropped downwardly i'rom theupwardly projecting part oi the L-shaped slot 19, thereby unlocking themechanism.

Extending through a suitable opening provided in a door is a cylindricalguide member 37 through which the casing L1 extends diametrically. Tothemember 3T is secured a cover plate by screws, pins or other suitablemeans.

1t 'frequently happens that a lock to be applied to various shaped doorstiles must be adjusted to tit the openings therein, and in such casesthe plunger must be ot suitable length. I have therefore constructed theplunger 14 in a plurality ot sections, so that the end thereotI may bebroken oli' in the event the distance from the tace plate 1 and theopening in the door through which the cylindrical guide member 37extends, is shorter than ordinarily. In such an event and in case thelock mechanism must be shortened, the casing 4 is moved toward the taceplate 1 until the projection 5 thereon becomes located in the one of theslots 3 of the tubular member i2 which affords the satisfactory lengththerefor. The nut 15, in the event the lock mechanism is to beshortened, may be screwed on the plunger by inserting a screw driverthrough the opening 88 in the casing 2.

lt is evident that the details of construction herein shown anddescribed may be modified in a variety of ways without departing fromthe spiritor scope of my invention; and desire it to be understood thatthe construction herein illustrated is but one lorm my improved loclrmay assume, and that I therefore desire my invention to be includedwithin the spirit ot the appended claims.
